Guild Wars 2

Better yet – make it into a game play element!
If someone takes something out of a guild stash, the guild can pay to put a contract on that persons head.

Step 1) Guild purchases an Assassin’s Contract – say 1 gold each
Step 2) Guild uses the Assassin’s Contract on someone who ‘withdrew’ from the stash
Step 3) Any where, any time, any situation, a Veteran Assassin can appear at the characters location and attempt to kill them. Only if the perpetrator dies, does the contract get fulfilled.
Step 4) Offer incentive to those around – say 5-10s if you help to fulfill the contract. It’s enough to make people target the perp, and stop any chance they have of ‘farming’ the Assassin (who also should give no loot).
Step 5) The guild is welcome to spend as much as they want on contracts

It might even be easy to implement using current game mechanics

You can have a tiny Asura if you like.. and your influence will be proportionally diminished by your diminutive size!

You’ll become a gnat vs a norn.

A circular map is just a square map in which you can’t get to the corners :-)

Yes, but only if it’s a significant yes.

I think an expansion pack should start at level 80 and progress perhaps up to level 150. The way I see it, the dynamic level adjustment accommodates for everything that might be introduced with an extra 70 or so levels.
When a current player moves into an expansion pack area, their level is shifted to minimum level 80. When a level 150 character moves back into original areas, just as it is now, their level is shifted down to the maximum for that zone.

There’s a need to progress characters upwards in an expansion pack, otherwise there would be an 80’s rush to the end to steam roll all the new content. So you have two options:

• Increase level of mobs, so a lvl150 mob destroys a lvl80 char
• Add a mechanism to slow progress, ie: Spectral Agony/Agony.

Option 1 infers a grind to get experience, however experience can be distributed in many other ways, which GW2 is great at.
Option 2 requires a gear check, which implies grind to gather the required gear. We have this currently with fractals and I personally think it doesn’t work.
